Benefits of technology

The present invention relates to a coupler for connecting shafts, which includes a virtual main axis, a coupler body, and a shaft socket with a leaf spring. The leaf spring is positioned at the coupler body to engage the surface of a plugged-in shaft. The coupler is designed to provide a secure and flexible connection between shafts, allowing for reduced friction and improved performance. The invention also includes a coupling device comprising a coupler and a shaft fitting with a leaf spring for enhanced stability and durability.

Problems solved by technology

However, identical radiuses of curvature require a high manufacturing precision and are thus hardly realized in practice.

Embodiment Construction

[0033]According to the present invention, a coupler for coupling shafts comprises a virtual main axis, a coupler body and a shaft socket provided in the coupler body. The first shaft socket comprises at least one leaf spring which is supported at the coupler body and which is configured and arranged for engaging a circumferential surface of a first shaft plugged in the first shaft socket. The at least one leaf spring has a direction of main extension extending tangentially to a virtual arc of a circle around the main axis. The first leaf spring of the coupler according to the invention has an essentially plane shape extending along its direction of main extension. The leaf spring is supported at the coupler body comprising the first shaft socket into which the first shaft can be plugged-in. Thus, the first leaf spring rotates together with the coupler body about the main axis. The leaf spring engages the circumferential surface of the first shaft extending around the main axis, i. e...

Abstract

A coupler for coupling shafts comprises a virtual main axis, a coupler body, and a shaft socket provided in the coupler body, which is configured and arranged for plugging-in a shaft along the main axis and which includes a leaf spring. The leaf spring has a direction of main extension extending tangentially to a virtual arc of a circle around the main axis. The leaf spring is rigidly supported at the coupler body, and configured and arranged for engaging a circumferential surface of the shaft plugged in the shaft socket.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]The present application is a continuation in part to international application PCT / EP2019 / 061709 entitled “Plug-In Coupling for Connecting Shafts”, filed on May 7, 2019 and claiming priority to German patent applications DE 10 2018 110 987.3 filed May 8, 2018 and DE 10 2018 112 084.2 filed May 18, 2018, both entitled “Steckbare Kupplung zur Verbindung von Wellen”.FIELD OF THE INVENTION[0002]The present invention relates to a plug-in coupler for connecting shafts.[0003]Such a coupler may be used for rigidly coupling a first shaft in rotational direction about a main axis to a second shaft or another component pivoting about the main axis coaxially with regard to the first shaft. To serve this purpose, the coupler has to be able to transfer torque between the first shaft, on the one hand, and the second shaft or the other component, on the other hand.[0004]The present invention also relates to such a coupler in which the coupling between th...
